How do you retrieve the filename of a file uploaded with st.file_uploader?

如果您上传单个文件（即accept_multiple_files=False），可以通过在返回的UploadedFile对象上使用.name属性来获取文件名：

import streamlit as st

uploaded_file = st.file_uploader("Upload a file")

if uploaded_file:
   st.write("Filename: ", uploaded_file.name)

如果您上传多个文件（即accept_multiple_files=True），可以通过在返回列表中的每个UploadedFile对象上使用.name属性来检索各个文件名：

import streamlit as st

uploaded_files = st.file_uploader("Upload multiple files", accept_multiple_files=True)

if uploaded_files:
   for uploaded_file in uploaded_files:
       st.write("Filename: ", uploaded_file.name)
